As you may remember, most of my in-ground trees were ravaged by voles. Here are two exceptions.
The first is Brooklyn White. It's a youngish tree that was put in-ground last year. During the winter it was protected under a "figloo." Note the nice breba. FWIW, I have a Sal's EL (not pictured) next to the BW that is in similar shape. It has a few tiny breba buds, each at the very tip of a branch, but I don't think they will survive.
The second is Gene's Paradiso. It's an air layer taken the summer before last, then put in the ground last year. During the winter it was not protected at all, other than being located on the NE side of a big rock (visible in background). There are small leaves (half dollar size) coming out of the younger wood, buds popping on the older wood. As far as I can tell, there was no winter damage. Note that there are a couple of tiny breba buds.
